Abstract
An anhydrous or aqueous composition containing at least one volatile fluoro compound in an amount of at least 0.5% by weight, and a process for make-up removal or for cleansing the skin, comprising (1) applying, preferably with the fingers, a pad of cotton wool, or a paper tissue, a sufficient amount of the composition to the parts of the skin to be cleansed or from which make-up is to be removed, (2) lightly massaging so as to detach the maximum amount of impurities and of the make-up product, and (3) removing the composition using a pad of cotton wool optionally soaked in water.

X is chosen from linear and branched perfluoroalkyl radicals containing from 2 to 5 carbon atoms, and
Z is chosen from O, S, or NR, wherein R is chosen from hydrogen and the radicals —(CH 2 ) n —CF 3 and —(CF 2 ) m —CF 3 , wherein m is 2, 3, 4, or 5.
8. A process according to claim 1 , wherein the at least one volatile fluoro compound is chosen from perfluoromorpholine derivatives of formula (IV):
in which:
R is a C 1 -C 4 perfluoroalkyl radical.
9. A process according to claim 5 , wherein the at least one volatile fluoro compound of formula (I) is chosen from perfluoromethylcyclopentane, perfluoro 1,3-dimethylcyclohexane, and perfluoro 1,2-dimethylcyclobutane.
10. A process according to claim 6 , wherein the at least one volatile fluoro compound of formula (II) is chosen from dodecafluoropentane, tetradecafluorohexane, and bromoperfluorooctyl.
11. A process according to claim 7 , wherein the at least one volatile fluoro compound of formula (III) is chosen from nonafluoromethoxybutane, and nonafluoroethoxyisobutane.
12. A process according to claim 8 , wherein the at least one volatile fluoro derivative of formula (IV) is 4-trifluoromethylperfluoromorpholine.
13. A process according to claim 1 , wherein the composition is in the form of an anhydrous oil containing the at least one volatile fluoro compound in soluble form or in a form which is finely dispersed in at least one cosmetic oil.
14. A process according to claim 13 , wherein the at least one cosmetic oil is chosen from non-fluoro oils which are miscible with the at least one volatile fluoro compound.
15. A process according to claim 14 , wherein the non-fluoro oils which are miscible with the at least one volatile fluoro compound are chosen from polysiloxanes.
16. A process according to claim 15 , wherein the polysiloxanes are chosen from volatile polydimethylsiloxanes and volatile hydrocarbon based oils.
17. A process according to claim 16 , wherein the volatile polydimethylsiloxanes are chosen from cyclopentasiloxane or cyclohexasiloxane.
